A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”. This idea is dangerous.  

Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.  

Some people go even further. They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ――somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it a fuels sense of  hopelessness and discourages them from making efforts to build a safer world.  

In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of “controlling” science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact （影响） on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict.  

Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.

A Chinese rocket carrying a probe（探测器）destined（预定） for the moon has been sent into space.

A Long March 3C rocket with the Chang’e -2 probe took off from Xichang launch centre at about 11: 00 GMT.

The rocket will shoot the craft into the trans-lunar orbit（绕月轨道）,  after which the satellite is expected to reach the moon in about five days.  Chang’e -2 will be used to test key technologies and collect data for future landings.  China says it will send a rover（漫游者） on its next mission,  and it also has ambitions to put humans on the surface of the lunar body at some future date.  The Xinhua News Agency said Chang’e -2 would circle just 15 km (nine miles) above the rocky terrain（地带）in order to take photographs of possible landing locations.

It is China’s second lunar probe—the first was launched in 2007. The craft stayed in space for 16 months before being intentionally crashed onto the moon’s surface. China launched its first manned flight into low-earth orbit in 2003; and two more followed, with the most recent one in 2008.  So far, only three countries have managed to independently send humans into space: China, Russia and the US.

In 2008, a Chinese astronaut, fighter pilot Zhai Zhigang, performed a spacewalk—the first in China’s history. He stayed outside the Shenzhou-7 capsule for 15 minutes; the exercise was seen as the key to China’s ambition to build an orbiting station in the near future.

71. What’s Chang’e -2’s main task according to this passage?

A. Landing on the moon just as the first lunar probe.

B. Comparing with the first lunar probe.

C. Competing with Russia’s and the US’s space crafts.

D. Testing technologies and collecting data for future landings.

72. Which of the following about Chang’e -2 is TRUE?

A. Its travel to the moon lasts about five days.

B. It will put humans on the surface of the moon.

C. It travels with Long March 3C rocket all the way.

D. It will take photographs of the moon on the trans-lunar orbit.

73. China’s first lunar probe_______ .

A. was launched in 2008

B. landed on the moon safely at last

C. took Chinese astronaut Zhai Zhigang to the moon in 2007

D. accomplished its task in less than one and a half years in space

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components(元件), ”said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.

Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis.”

72. The difficulty the team of engineers met with while making the robotic fly was that ________.

A. they had no model in their mind

B. they did not have sufficient time

C. they had no ready-made components

D. they could no assemble the components

A. consists of a flight device and a control system

B. can just fly in limited areas at the present time

C. can collect information from many sources

D. has been put into wide application

74. Which of the following can be learned from the passage?

A. The robotic flyer is designed to learn about insects.

B. Animals are not allowed in biological experiments.

C. There used to be few ways to study how insects fly.

D. Wood’s design can replace animals in some experiments.

75. Which of the following might be the best title of the passage?

A. Father of Robotic Fly

B. Inspiration from Engineering Science

C. Robotic Fly Imitates Real Life Insect

D. Harvard Breaks Through in Insect Study

Paris has the Eiffel Tower; New York has the Statue of Liberty; and Brussels, the Manneken

Piss.

Think of the Belgian capital and, if anything, you think of the small peeing (撒尿) boy ____  a 60-meter-high bronze figure standing on a block, supplying a constant stream of water to the basin under him.

Some might laugh. But for Jacques Stroobants, the statue is up there with the best of them.

“I’m proud of him. People come from all around the world to see him,” says 60-year-old Stroobants with a fatherly glance at the little boy.

As the most famous landmark of Brussels, Manneken Piss has a very special place in the heart of Belgians.

The original Manneken Piss dates back to 1388, but the statue tourists see today dates from 1619 when the city built a second one after the original was destroyed.

Many stories go round Manneken Piss. Nobody knows why he was made. One story is that he saved Brussels by putting out the flames of a deadly fire with his well-aimed piss. But the most believable story is that the boy, the son of a wealthy man, was kidnapped. The father had a statue built in honor of the way his son was found-peeing against a tree.

Perhaps best-known for his naked beauty, the “peeing boy” has also been clothed in some of the finest clothes money can buy.

Stroobants has been changing his clothes for the last 29 years. On average, he has clothes on 300 days a year. And on special days, he pees beer.

A few of the ways he’s been dressed are; a football player, Mozart and an army general. Now, he has more than 600 pieces of clothes.

There is no strict charge for those wishing to provide clothes for the little boy. But certain conditions must be met.

“The clothes cannot include either advertising or political message,” said Stroobants, because they would cheapen the national treasure.

But Manneken Piss is still something local people can make money from ___ by selling all kinds of souvenirs.

72. Which of the following is NOT true about Maneken Piss?

A. It has a history of more than 600 years.   B. It stands in Brussels. 

C. It is best known for the clothes he wears. D. It is 60 meters high.

73. The Manneken Piss has a special place in the heart of Belgians because          .

A. it’s good-looking with water running constantly

B. it brings joys to people who see it   

C. it helps people make beer

D. it’s a symbol of the city.

74. We can learn from the passage that          .

A. for most of the year, the boy is naked

B. Stroobants is probably in charge of taking care of the statue

C. people can provide any clothes for Manneken Piss

D. people make money by advertising Manneken Piss

75．Which of the following is not true according to the passage?

A. Tourists cannot provide clothes for the peeing boy.

B. The Manneken Piss has attracted many visitors.

C. The peeing boy is the national treasure of Belgium.

D. Local people make money by selling souvenirs.

     A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults.

     The researchers used a national long-term survey of adolescent（青少年的）health to investigate (调查)the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000.

     As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.

      Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one.

      The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio, etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use.

      The study didn't explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression.

      Last December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to he socially active, to read, attend religious services and to vote.

72. The best title for this passage should be____________.

     A. Teens, Television and Depression

     B. Men Develop Depression Easier than Women

     C. Media Use is Harmful to Adolescents

     D. Take Great care of Teenager's depression

73. The result of the research seems to prove______________.

    A. teenagers are more likely to develop depression than adults

    B. other media uses do no harm to adolescents

    C. TV probably causes teenagers to grow up with depression

    D. those who watch no TV will not develop depression

74. We can learn from the survey that of all the media use

    A. computer games are teenagers' favorite

    B. most teenagers prefer to listen to the radio

    C. teenagers enjoy watching TV very much

    D. newspaper is not included in the survey

75. We can conclude that a teenager should _____

    A. play more video games instead of watching TV

    B. be active in taking part in outdoor activities

    C. be more active in watching educational TV programmers

    D. attend religious services and care for politics
